続いてシステム制御回路１３は、ステップＳＰ４に移り、初期設定の位置よりこのフレーム数ｆにより特定されるフレーム番号を計算した後、ステップＳＰ５に移り、このフレーム番号により読み出しコマンドを発行した後、ステップＳＰ２に戻る。なおこのフレーム番号の特定は、サーチダイヤル１７Ｆの操作方向に応じて、初期設定の位置より時間軸方向に、又は時間軸を遡る方向に設定される。
【００９０】
これにより図１０において、各素材の先頭位置からの関係により処理対象の全フレーム数をｎとしてサーチダイヤル１７Ｆの操作と再生位置との関係を示すように、システム制御回路１３は、サーチダイヤル１７Ｆを反時計方向にいっぱいに回転させると（符号ＰＡにより示す）、処理対象の先頭フレーム（フレーム番号１）を再生するようにアクセス制御し、サーチダイヤル１７Ｆを時計方向にいっぱいに回転させると（符号ＰＢにより示す）、処理対象の最後尾フレーム（フレーム番号ｎ）を再生するようにアクセス制御する。またこの反時計方向にいっぱいに回転させた位置より時計方向に角度γだけ回転させると（符号ＰＣにより示す）、次式により表される、この回転角度γに対応するフレーム数ｋ−１だけ変位したフレーム番号ｋのフレームを再生するようにアクセス制御する。
【００９１】
【数２】

【００９２】
これらによりシステム制御回路１３は、サーチダイヤル１７Ｆの操作可能な範囲の上限及び下限に対して、処理対象である記録媒体４の再生結果における最先頭及び最後尾の時間情報が対応するように設定して、サーチダイヤル１７Ｆの操作方向及び操作量に応じて、記録媒体４へのアクセスを制御する。
【００９３】
かくするにつき、システム制御回路１３は、このようにしてサーチダイヤル１７Ｆの動作モードを操作子（ＤＰＣ）に対応する動作モードに設定した状態で、処理対象を選択する操作子１７Ａ及び１７Ｂの操作により処理対象が切り換えられると、上述した処理手順を同様に繰り返す。すなわちシステム制御回路１３は、サーチダイヤル１７Ｆの操作可能な範囲の上限及び下限に対応する設定した再生結果における第１及び第２の時間情報の値を、これら操作子１７Ａ及び１７Ｂの選択操作に応動して切り換える。
【００９４】
これによりシステム制御回路１３は、必要に応じて操作子１７Ａ及び１７Ｂを操作して処理対象を順次絞り込んで、簡易に編集点を設定できるようになされている。
【００９５】
（１−２）第１の実施の形態の動作
以上の構成において、編集装置１においては、編集対象の素材としてのＡＶ信号Ｓ１が（図１）、データ圧縮回路６において順次データ圧縮された後、一連のタイムコードによるフレーム番号が付加されてフレーム単位で記録媒体４に記録される。さらにこのときこのように記録した素材をアクセスするのに必要な素材リスト１４がエディター３で生成され、この素材リスト１４が記録媒体４に保存される。
【００９６】
このようにして記録媒体４に記録された素材は、各素材のフレームを特定するフレーム番号を付加した読み出しコマンドによりフレーム単位で読み出され、必要に応じてデータ伸張されて外部機器に出力され、またモニタ装置１１に表示される。これにより編集装置１においては、素材を確認しながら編集カットを設定して編集作業を実行することができる。
【００９７】
この編集カットの設定作業において、編集装置１においては、操作パネル１７において操作子（ＳＯＵＲＣＥ）の操作により素材側を選択すると（図４）、素材リスト１４を基準にした記録媒体のアクセスである素材側に処理して設定され、表示部１６（図３）において、この選択処理に応動して表示画面の左半分に割り当てられた素材側の領域が高輝度により表示される。この状態で例えば全素材を選択する操作子（ＡＬＬ）を選択した後、操作子（ＤＰＣ）を選択すると、サーチダイヤル１７Ｆがスライダの動作モードに設定される。すなわちサーチダイヤル１７Ｆが現在位置を基準にして時計方向及び反時計方向に所定角度範囲だけ操作できるように設定され、また全素材の中央に位置するフレームが記録媒体４より再生される。
【００９８】
この状態でサーチダイヤル１７Ｆを回転させると、サーチダイヤル１７Ｆの操作可能な範囲の上限及び下限に対して、再生結果における時間情報の最先頭の値及び最後尾の値が対応するように設定されて、サーチダイヤル１７Ｆの操作方向及び操作量に応じて記録媒体へのアクセスが制御される（図１０）。これにより編集装置１では、限られた回転操作可能な範囲の中でサーチダイヤル１７Ｆを回転させて、処理対象の先頭フレームより最後尾のフレームまで選択でき、必要とするフレームを大まかに選択することが可能となる。これによりランダムアクセス可能な記録媒体の特徴を充分に発揮して、従来のようにジョグダイヤル、シャトルダイヤルを操作する場合に比して格段的に迅速に所望のフレームを絞り込むことが可能となる。また素材の全体像についても、簡易かつ迅速に把握することが可能となる。
【００９９】
かくするにつきこのようにして選択したフレームについて、必要に応じて編集点の操作子１７Ｃを操作することにより、編集カットを設定することが可能となる。
【０１００】
またこのようにして選択したフレームがほぼ所望する場所のフレームではあるものの、これと前後するフレームを選択しようとする場合等にあっては、操作子（ＳＨＴＬ）、（ＪＯＧ）、（ＤＭＣ）を選択操作してサーチダイヤル１７Ｆの動作モードをシャトルダイヤル、ジョグダイヤルの動作モードに切り換えて、前後のフレームを検索することにより、必要に応じて所望の素材、フレームを選択することが可能となり、編集点を設定して編集カットを登録することが可能となる。
【０１０１】
このときスライダの動作モードと、シャトルダイヤル、ジョグダイヤルの動作モードとでサーチダイヤルの動作モードを切り換えたことにより、ランダムアクセス可能な記録媒体の特徴を充分に発揮して、従来のビデオテープレコーダによるジョグシャトルダイヤルと同一の操作感覚により所望のフレームを簡易に選択することができる。
【０１０２】
またこのようにして選択したフレームがほぼ所望する場所のフレームではあるものの、これと前後する素材のフレームを選択しようとする場合等にあっては、シャトルダイヤル、ジョグダイヤルとしてのサーチダイヤル１７Ｆの操作に代えて、送りの操作子１７Ｄ（ＩＮＤＥＸ ＦＷＤ）、（ＩＮＤＥＸ ＲＥＶ）を操作することにより、現在再生中の素材より操作子１７Ｄの操作に応動して再生中の素材を切り換えることが可能となる。この場合、多くの素材より所望する素材を迅速に選択して頭出しすることができる。
【０１０３】
これによりこの送りの操作子１７Ｄ（ＩＮＤＥＸ ＦＷＤ）、（ＩＮＤＥＸＲＥＶ）の操作により選択した素材について、操作子（ＳＨＴＬ）、（ＪＯＧ）、（ＤＭＣ）を選択操作してサーチダイヤル１７Ｆの動作モードをシャトルダイヤル、ジョグダイヤルの動作モードに切り換えて、前後のフレームを検索することにより、必要に応じて所望のフレームを選択することが可能となり、編集点を設定して編集カットを登録することが可能となる。
【０１０４】
このとき操作子（ＳＨＯＴ）の操作により、再生中の１つの素材を処理対象として選択すれば、シャトルダイヤル、ジョグダイヤルの動作モードにおけるサーチダイヤル１７Ｆの回し過ぎを防止することが可能となり、これによっても使い勝手を向上することが可能となる。
【０１０５】
またこのように所望する素材を選択した状態で操作子（ＤＰＣ）を選択すると、サーチダイヤル１７Ｆがスライダの動作モードに設定され、今度はこの選択した１つの素材について、サーチダイヤル１７Ｆの操作可能な範囲の上限及び下限に対して、再生結果における時間情報の最先頭の値及び最後尾の値が対応するように設定されて、サーチダイヤル１７Ｆの操作方向及び操作量に応じて記録媒体へのアクセスが制御される。
【０１０６】
これにより編集装置１においては、限られた回転操作可能な範囲の中でサーチダイヤル１７Ｆを回転させて、１つの素材の先頭フレームより最後尾のフレームまで選択でき、必要とする素材を大まかに把握し、また必要とするフレームを簡易かつ迅速に選択することが可能となる。
【０１０７】
かくするにつき編集装置１においては、このようにスライダの動作モードによりサーチダイヤル１７Ｆを動作させるにつき、処理対象を全素材より１つの素材に順次切り換えることにより、素材の全体像を把握して必要とするフレームを素材全体より簡易に絞り込むことができる。
【０１０８】
なおこのような全素材を対象としたサーチダイヤル１７Ｆのスライドモードによる絞り込みに代えて、従来と同様のシャトルダイヤル、ジョグダイヤルの動作モードによるサーチダイヤル１７Ｆの操作により所望の素材を選択した後、操作子（ＳＨＯＴ）、操作子（ＤＰＣ）の操作により、選択した素材を処理対象としてサーチダイヤル１７Ｆをスライダの動作モードに設定しても、素材の全体像を把握して必要とするフレームを素材全体より簡易に絞り込むことができ、この場合は従来のビデオテープレコーダにおける操作と同様にして素材を絞り込んだ後、この編集装置１に特有のスライダの機能によりフレームを絞り込むことが可能となる。
【０１０９】
ところでこのようにして素材を選択してはみたものの、所望する素材と異なる場合も考えられ、この場合は、操作子１７Ｄ（ＩＮＤＥＸ ＦＷＤ）、（ＩＮＤＥＸ ＲＥＶ）の操作により処理対象の素材を近傍の素材に切り換えて所望の素材を選択することができ、また操作子（ＡＬＬ）の操作等により改めて全素材より所望の素材を選択することができる。
【０１１０】
このようにして所望する素材よりフレームを選択して操作子１７Ｃ（ＭＡＲＫＩＮ）、（ＭＡＲＫ ＯＵＴ）の操作によりカットを仮登録することができ、さらに操作子（ＥＮＴＥＲ）の操作によりこのカットを編集カットとして登録することが可能となる。
【０１１１】
この編集カットの登録において、いわゆるプレビューする場合は、操作子１７Ｂ（ＭＡＲＫ）の操作により処理対象を仮登録したカットに切り換えて、操作子１７Ｅ（ＰＬＡＹ）等を操作することにより、このカットをモニタすることが可能なる。このときサーチダイヤル１７Ｆの動作モードをシャトルダイヤル、ジョグダイヤルの動作モードに設定して、従来のビデオテープレコーダを用いた編集装置と同様にプレビューの処理を実行することができる。
【０１１２】
このとき操作子（ＤＰＣ）の操作により、サーチダイヤル１７Ｆがスライダの動作モードに設定され、今度はこの仮登録したカットについて、サーチダイヤル１７Ｆの操作可能な範囲の上限及び下限に対して、再生結果における時間情報の最先頭の値及び最後尾の値が対応するように設定されて、サーチダイヤル１７Ｆの操作方向及び操作量に応じて記録媒体へのアクセスが制御される。
【０１１３】
これにより必要に応じてサーチダイヤル１７Ｆを回転させて、１つのカットの全体像を簡易に把握することができる。また順次このサーチダイヤル１７Ｆの処理対象を全素材、１つの素材、１つのカットに絞り込むことにより、素材の全体像を把握して必要とするフレームを素材全体より絞り込んだ後、その結果を簡易に確認することができ、また必要に応じて処理対象をカットより元の１つの素材、全素材に戻して確認する等により、仮登録したカットを迅速な処理により種々に検討することが可能となる。これによってもランダムアクセス可能な記録媒体の特徴を充分に発揮して、使い勝手を向上することができる。
【０１１４】
かくしてこのような処理の繰り返しにより編集装置１では、素材より編集カットが順次作成され、さらには編集結果より編集カットが作成され、これら編集カットが順次登録されて編集リスト１５が作成される。
【０１１５】
編集装置１においては、このように作成した編集リスト１５による編集結果を確認する場合、さらには編集結果よりさらに編集カットを作成する場合、操作子（ＰＲＯＧＲＡＭ）の操作により処理対象が編集結果に切り換えられ、素材側の素材リスト１４を基準にしたアクセスに代えて、編集リスト１５を基準にして記録媒体４がアクセスされる。またこの選択処理に応動して表示部１６（図３）において、表示画面の右半分に割り当てられた編集結果側の領域が高輝度により表示される。
【０１１６】
この状態で例えば全素材を選択する操作子（ＡＬＬ）を選択した後、操作子（ＤＰＣ）を選択すると、サーチダイヤル１７Ｆがスライダの動作モードに設定され、現在位置を基準にして時計方向及び反時計方向に所定角度範囲だけ操作できるようにサーチダイヤル１７Ｆが設定され、また編集結果の中央に位置するフレームが記録媒体４より再生される。
【０１１７】
この状態でサーチダイヤル１７Ｆを回転させると、サーチダイヤル１７Ｆの操作可能な範囲の上限及び下限に対して、編集結果における時間情報の最先頭の値及び最後尾の値が対応するように設定されて、サーチダイヤル１７Ｆの操作方向及び操作量に応じて編集リスト１４に従って記録媒体へのアクセスが制御され（図１０）、これにより限られた回転操作可能な範囲の中でサーチダイヤル１７Ｆを回転させて、編集結果の先頭フレームより最後尾のフレームまで選択でき、編集結果の全体像を簡易かつ迅速に把握することが可能となる。これによりランダムアクセス可能な記録媒体の特徴を充分に発揮して、使い勝手を向上することが可能となる。
【０１１８】
このような編集結果側を処理対象とした場合でも、編集装置１においては、素材側を処理対象とした場合と同様にして、全体より順次編集カット、所望するフレームを絞り込んで編集点を設定することにより、編集結果より所望のカットを仮登録し、さらにはこの仮登録したカットを確認して編集カットに登録することができる。
【０１１９】
また操作子１７Ｅ、ジョグダイヤル、シャトルダイヤルとしてのサーチダイヤル１７Ｆの操作により、従来のビデオテープレコーダによる編集装置の場合と同様に、編集結果を確認することができる。
【０１２０】
さらにこのとき、素材側を処理対象とした場合と同様にしてスライダの動作モードによりサーチダイヤル１７Ｆを操作すると共に、操作子（ＡＬＬ）、（ＳＨＯＴ）、（ＭＡＲＫ）の操作により処理対象を順次絞り込んで、さらには送りの操作子１７Ｄ（ＩＮＤＥＸ ＦＷＤ）、（ＩＮＤＥＸ ＲＥＶ）の操作により処理対象を切り換えて、簡易かつ迅速に編集結果、各編集カット、編集結果より生成したカットの全体像を把握してプレビューすることができ、また処理対象の絞り込みよって全体像との対比により各編集カット等を検討することができる。これによってもランダムアクセス可能な記録媒体の特徴を充分に発揮して、使い勝手を向上することができる。
【０１２１】
かくするにつき編集作業においては、このような編集点の設定、プレビューの処理が大部分を占めることにより、このようにして使い勝手を向上することにより、編集作業に要する時間を格段的に短縮することができる。
【０１２２】
（１−３）第１の実施の形態の効果
以上の構成によれば、回転操作子であるサーチダイヤルにおける操作可能範囲の上限及び下限が全素材の最先頭及び最後尾、１つの素材の最先頭及び最後尾等に対応するように切り換えて、この操作子の操作に応動して記録媒体をアクセス制御することにより、全体像を簡易に把握して所望するフレームを迅速に選択することができ、これによりランダムアクセス可能な記録媒体の機能を充分に発揮して一段と使い勝手を向上し、その分編集作業に要する時間を短縮することができる。
【０１２３】
また素材側と編集結果とにより処理対象を切り換えたことにより、素材よりカットを選択する場合だけでなく、編集結果を確認する場合でも、迅速かつ簡易な操作により全体像を把握して確認することができ、これによりランダムアクセス可能な記録媒体の機能を充分に発揮して一段と使い勝手を向上し、その分編集作業に要する時間を短縮することができる。
【０１２４】
さらにこのような素材と編集結果とについて、同一の操作により順次処理対象を切り換えて所望するフレームを絞り込めるようにして、このとき素材側と編集結果側とで対応する表示形態により表示を切り換えて時間情報等を表示することにより、統一的な操作により編集装置１を使用することができ、その分使い勝手を向上することができる。
【０１２５】
またこのようにサーチダイヤルをスライダの動作モードに設定して処理対象を切り換えるにつき、操作子（ＩＮＤＥＸ ＦＷＤ）、（ＩＮＤＥＸ ＲＥＶ）の操作によっても素材、編集カットである処理対象を切り換えることにより、迅速に素材、編集カットを選択することができ、このことによってもランダムアクセス可能な記録媒体の機能を充分に発揮して一段と使い勝手を向上し、その分編集作業に要する時間を短縮することができる。
【０１２６】
またこのとき従来のジョグシャトルダイヤルと１つの操作子を共用したことにより、ランダムアクセス可能な記録媒体の機能を充分に発揮して使い勝手を向上でき、さらにこのとき従来のビデオテープレコーダによる編集装置と同様の使い勝手を確保することができる。
【０１２７】

BACKGROUND OF THE INVENTION
The present invention relates to a playback device, an editing device, a playback device control method, and an editing device control method, and can be applied to a nonlinear editing device using a recording / playback device having a random access function, such as a hard disk device. In the present invention, the upper and lower limits of the operable range of the operator are switched so as to correspond to the top and bottom of all materials, the top and bottom of one material, etc. Thus, by controlling the access of the recording medium, the functions of the randomly accessible recording medium can be fully exhibited and the usability can be further improved.
[0002]
[Prior art]
In recent years, in the editing field in broadcasting stations, so-called non-linear editing work using a recording / reproducing apparatus having a random access function such as a hard disk device or an optical disk device has been performed instead of editing work using a video tape recorder which is difficult to access randomly. It is made to be adopted.
[0003]
That is, in this kind of editing work, after recording various materials to be edited on one recording / reproducing apparatus, these materials are selected while reproducing the various materials recorded in this way. Set. In the editing operation, each editing cut constituting the editing result is set by such editing point setting. Further, in the editing work, an edit list describing the edit point of each edit cut and the reproduction order of each edit cut is generated, and the edit result is generated by sequentially reproducing each edit cut according to the edit list. It is made like that.
[0004]
In editing work using a video tape recorder, the jog shuttle dial is operated to rapidly feed the magnetic tape, frame-by-frame, etc., so that a desired material can be selected and editing points can be set. A preview of the results has been made.
[0005]
On the other hand, in editing work using a hard disk device or the like, this kind of processing can be executed mainly by displaying a screen using a GUI (Graphical User Interface) and operating a pointing device such as a mouse on the screen. Has been made.
[0006]
In this way, although the operations in the editing work are different, in the non-linear editing using a hard disk device that can be randomly accessed, the overall picture of the material can be quickly grasped compared to the editing work using a video tape recorder. The time required for the editing work can be shortened because the selection of the material, the setting of the editing point, and the like can be performed quickly.
[0007]
[Problems to be solved by the invention]
By the way, in the operation using the GUI and the pointing device, there is a drawback that the operability is inferior to the operation by the jog shuttle dial.
[0008]
That is, the jog shuttle dial is a rotary operator that functions as a jog dial or shuttle dial by a user's selection operation. The jog dial is an operator that changes the playback position in the time axis direction or in the reverse direction by an amount corresponding to the clockwise or counterclockwise rotation operation amount during playback using a still image. The shuttle dial is an operator that changes the playback speed according to the clockwise or counterclockwise rotation angle during playback at the standard playback speed.
[0009]
With such operations, the jog shuttle dial can intuitively grasp and process events that are currently in progress and events that are around the time of the current event. Therefore, it can be considered as an extremely suitable operator for the process of selecting the preceding and following frames.
[0010]
Thus, it is considered that the non-linear editing work can be further improved by applying the jog shuttle dial to the non-linear editing apparatus used for the non-linear editing work to improve the operability.
[0011]
At this time, not only the function of the video tape recorder is applied to the non-linear editing apparatus, but also in the case of using the magnetic tape so that the convenience of the randomly accessible recording medium can be fully exhibited. If such a function can be added, the usability of this type of editing apparatus can be further improved.
[0012]
The present invention has been made in consideration of the above points, and can provide a playback device, an editing device, a playback device control method, and a playback device that can fully improve the usability by fully exhibiting the functions of a randomly accessible recording medium. The present invention intends to propose a control method for an editing apparatus.
[0013]
[Means for Solving the Problems]
In order to solve this problem, the present invention is applied to a playback device, an editing device, a control method for a playback device, or a control method for an editing device. Is set so that the first and second values of the time information in the reproduction result correspond to each other, and the access to the recording medium is controlled in accordance with the operation direction and the operation amount of the operation element, and responds to a predetermined selection operation. Then, the first and second values are switched.
[0014]
By setting the first and second values of the time information in the reproduction result of the recording medium to correspond to the upper and lower limits of the operable range of the operation element, the operation direction and operation amount of the operation element are set. If the access to the recording medium is controlled accordingly, the first and second values are set, for example, at the very beginning and the end of the signal recorded on the recording medium, and the whole is responded to the operation of the operator. The image can be grasped quickly and easily. At this time, if the first and second values are switched in response to a predetermined selection operation, the entire material recorded on the recording medium, one material, and the like can be selected and accessed as necessary.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
[0016]
(1) First Embodiment (1-1) Configuration of the First Embodiment FIG. 1 is a block diagram showing an editing apparatus according to the first embodiment of the present invention. In the editing apparatus 1, the recording / reproducing apparatus 2 is a randomly accessible recording / reproducing apparatus that records and reproduces a video signal and an audio signal accompanying the video signal (hereinafter referred to as an AV signal). Operates by control.
[0017]
That is, the recording / reproducing apparatus 2 sequentially records the AV signal S1 based on an analog signal or a digital signal or the AV signal S1 compressed in data on the recording medium 4 under the control of the editor 3, thereby various materials to be edited. Are sequentially accumulated.
[0018]
The input circuit 5 performs analog-digital conversion processing on the analog AV signal S1 and outputs it to the subsequent data compression circuit 6, whereas the AV signal S1 based on digital signal omits the analog-digital conversion processing and continues data compression. Output to circuit 6.
[0019]
The data compression circuit 6 compresses and outputs the AV signal S1 output from the input circuit 5 to a predetermined data amount. Here, the compression format of the data compression is determined in consideration of the recording capacity of the recording medium for recording the AV signal S1, the recording / reproducing speed, connectivity with other systems, and the like. For example, the DV format 25 [Mbps] MPEG (Moving Picture Experts Group) 2 format 50 [Mbps] can be applied as necessary.
[0020]
In this embodiment, the data compression circuit 6 encodes consecutive frames only by intra-frame encoding processing so that the number of frames of 1 GOP (Group Of Pictures) becomes one frame by the MPEG2 method. As a result, the recording / reproducing apparatus 2 can reproduce and output a desired frame more quickly than in the case of assigning an inter-frame encoding process.
[0021]
The input / output interface (input / output I / F) 7 records the AV signal S 1 output from the data compression circuit 6 on the recording medium 4. Here, a hard disk, an optical disk, a semiconductor memory element, or the like that can be randomly accessed is applied as the recording medium 4, and a hard disk is applied in this embodiment.
[0022]
When recording the AV signal S1 in this manner, the input / output interface 7 reproduces the corresponding AV signal S1 in units of frames in response to an access from the editor 3 based on the time code by a simple process. Each frame is assigned an address with a frame number so that it can be output. Here, the frame number is a number for specifying one frame by the hour, minute, second and frame of the time code. At this time, a continuous time code is assigned to each material recorded on the recording medium 4 under the control of the editor 3 (that is, the AV signal S1 recorded continuously), and a frame number is assigned by this time code to each frame. Record.
[0023]
Further, when the recording of one material by the continuous AV signal S1 is completed, the input / output interface 7 notifies the first frame number and the last frame number by data communication with the editor 3, and responds to this notification. The material list recorded on the recording medium 4 is updated under the control of the editor 3. Here, the material list is a table necessary for the access control of each material recorded in this way from the editor 3 side. At least the continuous material number, the top frame number of each material, Consists of frame numbers.
[0024]
In addition, the input / output interface 7 records and updates the editing list necessary for reproducing the editing result on the recording medium 4 in the same manner under the control of the editor 3 in correspondence with the material list for specifying each material to be edited. Here, the edit list is a list necessary for accessing the material recorded on the recording medium from the editor 3 and reproducing it as an edit result. At least the frame number for specifying the edit point set by the operator and the edit list It consists of a number that specifies the playback order of a series of AV signals (that is, one edit cut) specified by points, the connection form of successive edit cuts, and the like.
[0025]
The input / output interface 7 reproduces these material lists and edit lists and outputs them to the editor 3 at the request of the editor 3 when the power is turned on.
[0026]
In addition, the input / output interface 7 receives the AV signal S1 recorded on the recording medium in accordance with the read command by the frame number added at the time of recording in the access of the editor 3 according to the material list and the edit list output to the editor 3 in this way. Play and output frame by frame. As a result, in the recording / reproducing apparatus 2, for example, when outputting the AV signal S1 of the NTSC system, the read control command is received at a 1/30 second period and the corresponding AV signal S1 is output. Yes.
[0027]
The input / output interface 7 directly inputs the data-compressed AV signal S1 from the external device, records the AV signal S1 on the recording medium 4 in the same manner as described above, and transmits the AV signal S1 to the external device in the form of the data compressed. Is output directly from the recording medium 4 to the external device.
[0028]
The data decompression circuit 8 decompresses and outputs the AV signal S1 output from the input / output interface 7, and the output circuit 9 outputs the AV signal S1 to an external device. At this time, the output circuit 9 performs digital-analog conversion processing on the AV signal S1 as necessary, and outputs it as an analog signal.
[0029]
As a result, the recording / reproducing apparatus 2 can reproduce and output the AV signal S1 recorded on the recording medium 4 under the control of the editor 3.
[0030]
The monitor device 11 can monitor the AV signal S1 output from the recording / reproducing device 2.
[0031]
The editor 3 controls the operation of the recording / reproducing apparatus 2 by the system control circuit 13 according to the operation of the operator, thereby recording various materials and updating the material list on the recording medium 4.
[0032]
The editor 3 acquires the material list recorded on the recording medium 4 as needed and expands it in a built-in memory. The editor 3 issues a control command to the recording / reproducing apparatus 2 by the operation of the operator in accordance with the material list 14 developed in the memory and the editing list 15 created by the operation of the operator, and thereby the material recorded on the recording medium 4 Play edit cuts, etc. The editor 3 instructs the recording medium 4 to record the edit list 15 at a predetermined timing.
[0033]
The editor 3 displays various information necessary for creating this edit list on the display unit 16 and inputs an operator's operation via the operation panel 17.
[0034]
As a result, as shown in FIG. 2, the editing apparatus 1 assigns continuous time codes and records various materials A, B, and C on the recording medium 4 (FIG. 2A), and then operates the editor 3. These materials A, B, and C can be reproduced and monitored by the monitor device 11. Further, the editing points are set by the editor 3 with reference to the monitoring result to set the editing cuts a, b, c, and d (FIG. 2B), and the editing cuts a and b set in this way are set. , C, d can create an edit list, and according to this edit list, the edit cuts a, b, c, d can be reproduced sequentially and the edit result can be output (FIG. 2C). ).
[0035]
FIG. 3 is a plan view showing an example of a display screen of the display unit 16 that displays various information necessary for creating an edit list in the editor 3. In this display screen, an edit processing mode (EDIT MODE) area is formed at the bottom, and displays indicating the edit modes of assemble (ASSEMBLE), insert (INSERT), and over (OVER) are arranged in this area. It is made like that. On the display screen, these displays are selectively displayed with high brightness in response to an operator's selection operation on the operation panel 17.
[0036]
In the display screen, the remaining area to which the editing mode is assigned in this way is divided into two areas on the left and right from the center. It is assigned to display time information related to the editing result. In these areas on the left and right sides of the center, corresponding items regarding the material and the editing result are arranged side by side, thereby improving the usability of the operator. Further, in the areas related to these materials and editing results, the corresponding areas are selectively high when outputting the reproduction results for the materials in response to the operation of the operation panel 17 and when outputting the reproduction results for the editing results. The display is based on the brightness, and this also improves the usability.
[0037]
Here, in the area related to the material on the left side, a display (SOURCE) indicating that the display unit is related to the material is arranged on the center side and the upper part of the display screen. Further, a time code display area is formed below the display.
[0038]
Here, in this time code display area, the time code (00: 00: 00: 00) continuous for all materials for the currently accessed frame (time continuous for the materials A, B, and C described above with reference to FIG. 2). Is displayed), and the time code type is displayed next to the time code (TC CTL UB). Further, a display (SHOT / TOTAL) indicating the currently accessed material among all the materials is arranged under the time code display. Here, the 456th material is recorded in the recording / reproducing apparatus 2, and the 123rd It shows that you are currently accessing the material. Further, in the time code display area, a display (SCOPE) indicating the unit in which the currently accessed frame is accessed is formed along with this, and all the materials recorded in the recording / reproducing apparatus 2 are targeted. Display (ALL) indicating access that has been changed, display (SHOT) indicating access in units of the currently accessed material, and display (MARK) indicating access in units of cuts based on set edit points Has been made. The display (ALL), (SHOT), and (MARK) are selectively displayed with high brightness in response to the operation of the operation panel 17 on the display screen.
[0039]
On the display screen, information related to the edit point is displayed below the display area of the time code. That is, on the display screen, a display indicating the IN point (MARK IN), a display of the corresponding time code, a display indicating the OUT point (MARK OUT), and a display of the corresponding time code are arranged side by side. Further, below these displays, a display indicating the length between the IN point and the OUT point (MARK DURATION) and a corresponding time code display are arranged. On the display screen, a display regarding these edit points is selectively displayed with high luminance in response to an operation on the operation panel 17.
[0040]
On the other hand, in the area related to the editing result on the right side, a display (PROGRAM) indicating that the display unit is related to the editing result is arranged on the center side and upper part of the display screen. Further, a time code display area and a display area related to editing points are formed below the display corresponding to the display on the material side. In the time code display area and the edit point display area, since these pieces of information are information related to the edit result that is a set of edit cuts, “CUT” is used instead of “SHOT” on the material side. Characters are assigned and displayed, and other than the display of the characters, the display is the same as the display on the material side.
[0041]
FIG. 4 is a plan view showing an arrangement of main operation elements of the operation panel 17. The operation panel 17 is configured similar to an operation panel of an editor used in an editing apparatus using a video tape recorder, and various operators are arranged in addition to the illustrated operators. That is, on the operation panel 17, an operator 17A for selecting a processing target is arranged on the upper left. Here, these operators 17A are composed of an operator (SOURCE) for selecting the material side as a processing target and an operator (PROGRAM) for selecting the editing result side as a processing target. In the editor 3, the left half and the right half of the display screen described above are selectively displayed with high luminance in response to the operation of the operation element 17A.
[0042]
On the operation panel 17, an operator 17B for selecting a processing target in more detail is arranged below the operator 17A for selecting the processing target. Here, the operation element 17B is an operation element (ALL) for selecting the entire material selected by the operation element 17A or the entire editing result as a processing target, and one of the material or the editing result selected by the operation element 17A. Operator (SHOT) to be selected as a processing target, operator (MARK) for processing a cut designated by an operator at an editing point arranged on the lower side of the material or editing result selected by the operator 17A It consists of.
[0043]
Corresponding to this, at the bottom of the operation panel 17, an operation element 17C relating to setting of the edit point is arranged. Here, the operator 17C has an operator (MARK IN) for setting and updating the IN point, an operator (MARK OUT) for setting and updating the OUT point, and a cut specified by the setting of the IN and OUT points. It is composed of an operator (ENTER) registered as an edit cut.
[0044]
On the operation panel 17, an operation element 17 </ b> D for switching a material being reproduced or an edit cut is arranged on the operation element 17 </ b> C at the editing point. Here, the operation element 17D includes a forward feed operation element (INDEX FWD) for switching the material or the edit cut in the direction along the time axis and switching the material or the edit cut in the direction going back on the time axis. It consists of a reverse feed operator (INDEX REV) that cues.
[0045]
Thus, as indicated by the symbol F in FIG. 5, the editor 3 operates the forward feed operator (INDEX FWD) with the material selected by operating the operator 17A, etc. The material can be sequentially switched from the position in the direction of the time axis, and similarly, as indicated by the symbol R, the reverse feed operator (INDEX REV) is operated to The material can be cued by switching the material in the direction of going back the time axis sequentially from the position.
[0046]
On the other hand, as indicated by reference numeral F in FIG. 6, in the state where the editing result is selected by the operation of the operation element 17A, the forward feed operation element (INDEX FWD) is operated to sequentially start from the currently reproduced position. The editing cut can be switched to the beginning in the time axis direction, and similarly, as indicated by the symbol R, the reverse feed operator (INDEX REV) is operated to start from the current playback position. The editing cut can be switched in the direction of going back in time sequentially so that it can be cued. In the operation of the operator (INDEX REV), after the playback position is switched to the beginning of the currently reproduced material and the edit cut by a single pressing operation, the material and The editing cut can be cued.
[0047]
On the other hand, on the operation panel 17, an operation element 17E for reproduction or the like similar to that of the video tape recorder is arranged on the right side of the operation element 17A for selecting a processing target. That is, these operation elements 17E include a recording operation element (REC), a reproduction operation element (PLAY), a still image temporary stop operation element (STILL), a rewind operation element (REV), and a fast-forward operation element ( FF) is arranged.
[0048]
Thus, in this editor 3, for example, when the material side is selected by the operation element 17A (SOURCE) and the whole is selected by the operation element 17B (ALL), when any of these operation elements 17D is operated, this selection is made. The entire material can be fast forwarded, rewound, reproduced, etc., according to the operation element 17D.
[0049]
Alternatively, for example, when the material side is selected by the operation element 17A (SOURCE) and one material is selected by the operation element 17B (SHOT), and one of these operation elements 17D is operated, the selected 1 Similar processing can be executed for two materials. Further, for example, after selecting the material side with the operation element 17A (SOURCE) and selecting the cut with the operation element 17B (MARK), if any one of these operation elements 17D is operated, it is still registered by the operation point 17C of the editing point. The same processing can be executed for the uncut cuts.
[0050]
On the other hand, for example, when the editing result side is selected by the operation element 17A (PROGRAM) and the whole is selected by the operation element 17B (ALL), when one of these operation elements 17D is operated, By executing the same processing, so-called preview, recording of the edited result on a video tape recorder, and the like can be executed.
[0051]
Further, for example, the edit result side is selected by the operation element 17A (PROGRAM) and one edit cut is set by the operation elements 17B (SHOT) and (MARK), or the edit point operation element 17C is set for the edit result. Cuts that have not yet been registered can be fast forwarded, rewound, reproduced, etc., according to the operation element 17D.
[0052]
The operation panel 17 is provided with a mode switching operator 17G for switching the operation mode of the search dial 17F under the operation 17E for reproduction and the like. Here, the operation element 17G includes an operation element (SHTL) for setting the search dial 17F to the shuttle dial operation mode, an operation element (JOG) for setting the search dial 17F to the operation mode for the jog dial, and the degree of speed change with respect to the rotation angle. And an operator (DMC) for setting the search dial 17F to the jog dial operation mode and an operator (DPC) for setting the search dial 17F to the slider operation mode.
[0053]
Here, the slider operation mode is set such that the rotatable range is set in the search dial 17F, and this rotatable operation range corresponds to the change range of the time information in the processing target selected by the operating elements 17A and 17B. And an operation mode for reproducing the processing target from the recording / reproducing apparatus 2.
[0054]
Correspondingly, the operation panel 17 is provided with a search dial 17F below the operation elements 17G. In the search dial 17F, for example, 270 degrees or more as a whole in the operation mode of the shuttle dial and the slider. While the rotatable range is restricted so that it cannot be rotated, in the jog dial operation mode, the restriction of the rotatable range is released by releasing the clutch arranged on the rotating shaft so that it can rotate freely. ing. In the search dial 17F, a rotary encoder arranged on the rotary shaft constitutes an operation amount detection means, and the operation amount is detected by the rotary encoder.
[0055]
Accordingly, in the editor 3, as shown in FIGS. 7A and 7D, for example, the material side is selected by the operation element 17A and the whole is selected by the operation element 17B, and the search is performed by the operation of the operation element 17G. When the operation mode of the dial 17F is set to the operation mode of the slider, the search dial 17F can be rotated within the predetermined range of rotation operation to reproduce any frame in all the materials. In other words, in this case, the search dial 17F can be rotated counterclockwise until it becomes difficult to rotate, and the first frame in all the materials can be reproduced, and conversely, the search dial 17F is difficult to rotate clockwise. To the last frame in all materials.
[0056]
Also, as shown in FIGS. 7B and 7D, for example, when the material side is selected by the operation element 17A and one material is selected by the operation element 17B, the one material to which the frame currently being reproduced belongs is selected. By operating the search dial 17F according to the operation mode of the slider, any frame in this one material can be reproduced.
[0057]
Further, as shown in FIGS. 7C and 7D, for example, when the material side is selected by the operation element 17A and the cut is selected by the operation element 17B, the cut is set by the operation of the operation element 17C and is not yet performed. For registered cuts (cuts in the section designated by the IN point IN and OUT point OUT), the search dial 17F can be operated according to the operation mode of this slider to reproduce any frame in the cut. ing.
[0058]
Further, as shown in FIGS. 8A and 8D, for example, if the editing result side is selected by the operation element 17A and the whole is selected by the operation element 17B, the search dial 17F is set within the range in which the operation element 17G can be rotated. Any frame in the entire editing result can be played back by rotating.
[0059]
Further, as shown in FIGS. 8B and 8D, for example, when the editing result side is selected by the operation element 17A and one editing cut is selected by the operation element 17B, one editing cut to which the frame currently being reproduced belongs. In this case, the search dial 17F is operated in accordance with the operation mode of the slider so that an arbitrary frame in the one edit cut can be reproduced.
[0060]
Also, as shown in FIGS. 8C and 8D, for example, when the editing result side is selected by the operation element 17A and a cut is selected by the operation element 17B, the cut is set by the operation of the operation element 17C and is still For unregistered cuts (cuts in the section specified by the IN point IN and OUT point OUT), the search dial 17F can be operated by the operation mode of this slider so that any frame in the cut can be reproduced. Has been made.
[0061]
In addition to these operators 17A and the like, the operation panel 17 includes an operator for registering an edit cut registered by the operation of the operator 17B in an edit list, an operator for setting a time code, and the like. In 3, the editing operation desired by the operator can be executed.
[0062]
In the editor 3, the system control circuit 13 controls the overall operation by executing a series of processing procedures in response to the operation of the operation elements 17 </ b> A and the like. The processing corresponding to the operation of can be executed.
[0063]
That is, the system control circuit 13 controls the operation of the recording / reproducing apparatus 2 in accordance with the operation of the operation element arranged on the operation panel 17 to record the sequentially input AV signal S1 on the recording medium 4, thereby the editing material. Accumulate in the recording medium 4. Further, the material list 14 is created, and the material recorded on the recording medium 4 is reproduced by accessing the recording / reproducing apparatus 2 in accordance with the material list 14. Further, an edit cut is created by setting an edit point based on the reproduction result, and an edit list 15 is created so that an edit result based on a set of edit cuts can be output.
[0064]
In this series of processes, the system control circuit 13 increases the display of time information on the material side when an operation element (SOURCE) that selects the material side as the processing object is operated in the operation element 17A that selects the processing object. The recording medium 4 is selectively displayed according to the brightness, and the recording medium 4 is controlled in response to the operator's operation according to the material list 14.
[0065]
That is, in this state, the system control circuit 13 records the reproduction target when an operation element (ALL) that selects all materials or all edit cuts as the processing target is operated in the operating element 17B that selects the processing target in more detail. Set to all materials recorded on the medium 4. In this state, when the playback operation element 17E is operated, the system control circuit 13 sequentially issues a read control command to which a frame number is added according to the material list, and continues in this frame number in the order of the time code assigned at the time of recording. Specify frames sequentially. In addition, when the fast forward and rewind operators are operated instead of the reproduction operation element 17E, similarly, read control commands with skipped frame numbers are sequentially issued according to the material list 14, and thereby fast forward and rewind reproduction. The result is output from the recording / reproducing apparatus 2. On the other hand, in the case of temporary stop, a read command with the same frame number is issued sequentially, and the reproduction result by the still image is output from the recording / reproducing apparatus 2.
[0066]
On the other hand, in the operation element 17B for selecting the processing object in more detail, when an operation element (SHOT) for selecting one material as the processing object is operated, the reproduction object is set to the material currently being reproduced. In this state, when the playback operation element 17E or the like is operated, the system control circuit 13 executes processing such as playback, pause, fast forward, and rewind for the currently played back material according to the material list 14. In the same manner as described above, a read control command with a frame number added is issued.
[0067]
Instead, when an operator (MARK) whose cut is to be processed is operated, the cut set by the operation of the edit point setting operator 17C is set as a processing target. In this state, when the playback control 17E or the like is operated, the system control circuit 13 plays, pauses, fast forwards, rewinds, etc. the processing target according to the material list 14 and the set editing point. A read control command is issued in the same manner as described above.
[0068]
In addition, when the operator (PROGRAM) for selecting the editing result as the processing target is operated in the operating element 17A for selecting the processing target, the system control circuit 13 selectively displays the time information on the editing result side with high luminance. And the access control of the recording medium 4 in response to the operator's operation according to the edit list 15.
[0069]
In other words, the system control circuit 13 operates according to the edit list 15 when an operation element (ALL) for selecting all materials or all edit cuts as a process target is operated in the operation element 17B for selecting a process target in more detail in this state. Set all edit results as playback targets. In this state, when the playback operation element 17E is operated, the system control circuit 13 sequentially issues a read control command to which a frame number is added according to the edit list 15, and sequentially continues frames in the edit list in that frame number. specify. In addition, when the fast forward and rewind operators are operated instead of the playback operation element 17E, the read control commands with the skipped frame numbers are sequentially issued according to the edit list 15 in the same manner. The return playback result is output from the recording / playback apparatus 2. On the other hand, in the case of temporary stop, a read command with the same frame number is issued sequentially, and the reproduction result by the still image is output from the recording / reproducing apparatus 2.
[0070]
On the other hand, in the operation element 17B for selecting the processing object in more detail, when the operation element (SHOT) for selecting one material as the processing object is operated, the editing cut currently being reproduced is set as the reproduction object. In this state, when the playback operation element 17E or the like is operated, the system control circuit 13 executes processing such as playback, pause, fast forward, rewind, etc. for the edit cut currently being played according to the edit list 15. Similarly, a read control command is issued in the same manner as described above.
[0071]
Instead, when an operator (MARK) whose cut is to be processed is operated, the cut set by the operation of the edit point setting operator 17C is set as a processing target. In this state, when the playback control 17E or the like is operated, the system control circuit 13 plays, pauses, fast forwards, rewinds, etc. the processing target according to the editing list 15 and the set editing point. A read control command is issued in the same manner as described above.
[0072]
In the processing for these materials and editing results, the system control circuit 13 responds to the operation mode according to the material list 14 and the editing list 15 respectively when the operator 17D for switching the material being reproduced or the editing cut is operated. Add the frame number specifying the material before and after the current playback material and edit cut, the frame number specifying the first frame of the edit cut, or add the frame number specifying the current frame and the first frame of the edit cut. Then, a read control command is issued. Thus, the system control circuit 13 sequentially switches the material being reproduced and the edit cut in the direction along the time axis or in the direction going back along the time axis in response to the pressing operation of the operation element 17D.
[0073]
On the other hand, when the operating element 17C for setting the edit point is operated, the time code is recorded in a register or the like for the frame being reproduced at the time when the operating element 17C is operated, and the cut is temporarily registered. When an operator (ENTER) for registering this cut as an edit cut is operated, the temporarily registered cut is registered in the edit list, and various items necessary for creating the edit list such as the reproduction order are accepted.
[0074]
In this way, when reproducing the frame desired by the operator, the system control circuit 13 determines the time code, the currently reproduced material of all the materials for the currently reproduced frame in the display area corresponding to the processing target. The position or the position of the currently-edited editing cut in the entire editing cut is displayed on the display unit 16.
[0075]
If the shuttle dial operator (SHTL) is operated in a state where the reproduction operation element 17E is operated in this way to reproduce the material, the edited result, etc., the system control circuit 13 is arranged on the search dial 17F. The clutch is connected, and the operation mode of the search dial 17F is set to the operation mode of the shuttle dial. As a result, the system control circuit 13 sets the search dial 17F to rotate within a predetermined angle range, and the predetermined operation amount of the search dial 17F based on the predetermined reference position is a constant speed change amount in the time information of the reproduction result. The access to the recording medium is controlled according to the amount of operation of the search dial 17F.
[0076]
That is, the system control circuit 13 detects the operation amount at a 1/30 second period from the rotary encoder disposed on the search dial 17F, and thereby detects the operation amount of the search dial 17F at a constant time interval. At this time, the system control circuit 13 detects the operation amount based on the rotation angle of the search dial 17F with reference to a predetermined reference position (the midpoint position of the movable range).
[0077]
When the search dial 17F is rotated from the current position in the clockwise direction, the system control circuit 13 sequentially issues read commands based on skipped frame numbers at time intervals corresponding to the operation amount, whereas the search dial 17F Is rotated counterclockwise from the current position, a read command is issued by repeating the same frame number a predetermined number of times so that the frame number is reduced by a time interval corresponding to the operation amount. When the operation amount in the counterclockwise direction becomes equal to or greater than a predetermined value, a read command is issued by setting the frame number to decrease step by step at a time interval corresponding to the operation amount. Thus, the system control circuit 13 can easily select a desired scene by switching the playback speed by operating the search dial 17F.
[0078]
On the other hand, if the jog dial operator (JOG) is operated in a state where the playback operation element 17E is operated or a still image is displayed, the system control circuit 13 is arranged in the search dial 17F. The clutch is released and the operation mode of the search dial 17F is set to the operation mode of the jog dial. Thereby, the system control circuit 13 sets the search dial 17F so that it can be freely rotated, and the search dial 17F is set so that the predetermined operation amount of the search dial 17F corresponds to a certain amount of change in the time information of the reproduction result. The access to the recording medium is controlled according to the operation amount. When the jog dial operator (JOG) is operated while the playback operator is operated, the system control circuit 13 sets the operation mode to the still image operation mode and accepts the operation of the search dial 17F.
[0079]
In other words, the system control circuit 13 detects the operation amount at a period of 1/30 second from the rotary encoder arranged on the search dial 17F, and thereby determines the operation amount of the search dial 17F by the rotation angle of the search dial 17F at a constant time interval. To detect. When the search dial 17F is rotated clockwise from the current position for the still image that is the reproduction result, the system control circuit 13 starts from the frame number currently being reproduced by the amount of each operation detected in this way. On the contrary, when the search dial 17F is rotated counterclockwise from the current position, the current playback is performed by the amount of operation detected in this way. The read command is issued sequentially by reducing the frame number from the middle frame number. As a result, the system control circuit 13 can easily find the desired frame by changing the currently playing frame in the direction along the time axis or in the direction going back the time axis by the amount of rotation of the search dial 17F. Has been made.
[0080]
On the other hand, when the following operation element (DMC) is operated instead of the jog dial operation element (JOG), the system control circuit 13 similarly sets the operation mode of the search dial 17F to the operation mode of the shuttle dial. . Further, the system control circuit 13 reduces the change in the frame number so that the change amount of the reproduction speed with respect to the operation amount of the search dial 17F is reduced as compared with the case where the shuttle dial operator (SHTL) is operated. The read command is issued sequentially. As a result, the system control circuit 13 reproduces, for example, a fast-moving material such as a sport by so-called slow motion so that a desired frame can be accurately selected.
[0081]
When the operator (DPC) following this operation is operated, the system control circuit 13 connects the clutch disposed on the search dial 17F, and the search dial 17F is predetermined clockwise and counterclockwise from the current position. Only rotate the angle range.
[0082]
Further, the system control circuit 13 detects the total number of frames for the processing target currently being reproduced designated by the operators 17A and 17B with reference to the time codes of the material list and the edit list. That is, when all the materials are played back, the number of frames M from the beginning of the leading material to the tail of the last material is detected (FIG. 7A), and one material is played back. In this case, the number N of frames from the beginning to the end of the material is detected (FIG. 7B), and when the cut set for the material is reproduced, between the In point and the Out point. The number of frames O is detected (FIG. 7C).
[0083]
When all editing results are being reproduced, the number m of frames from the beginning of the first editing cut to the last of the last editing cut is detected (FIG. 8A). When playing back, the number n of frames from the beginning to the end of this edit cut is detected (FIG. 8B), and when the cut set for the edit result is played back, And the number o of frames between the out points is detected (FIG. 8C).
[0084]
Subsequently, the system control circuit 13 halves these frame numbers M to o, and calculates the time code at a position displaced in the time axis direction from the top of the processing target by the halved frame number. . Further, the system control circuit 13 issues a read command with the frame number based on the time code thus calculated. As a result, the system control circuit 13 performs access control so as to reproduce the central frame in the processing target currently being reproduced, and the center of the rotatable range that is the current position of the search dial 17F and the current reproduction position in the processing target. To correspond. When calculating the time code for the central playback position in this way, the editing result is that the number of frames for each edit cut is calculated because the time code is not continuous between edit cuts that are continuously played back. The total number of frames is calculated by addition, and the target time code is calculated by subtracting the number of frames of each edit cut from the total number of frames reduced to ½.
[0085]
When initialization is performed in this way, the system control circuit 13 subsequently executes the processing procedure shown in FIG. 9 at a period of 1/30 second, whereby the processing target currently being played back selected by the control elements 17A and 17B. The upper and lower limits of the operable range of the search dial 17F are set so as to correspond to the first and last time information, and the playback position is changed in response to the operation of the search dial 17F (FIGS. 7 and 7). 8).
[0086]
That is, the system control circuit 13 proceeds from step SP1 to step SP2, where the operation amount of the search dial 17F is detected from the rotary encoder of the search dial 17F. Here, the system control circuit 13 detects the operation amount based on the rotation angle β based on the center of the initially settable rotatable range.
[0087]
Subsequently, the system control circuit 13 executes the following arithmetic processing based on the corresponding total number of frames F (M, N, O, m, n, o) calculated by the initial setting, whereby the search dial 17F can be rotated. Assuming that all the frames to be processed are assigned equally to the angle α, the number of frames f corresponding to the rotation angle β is calculated. Here, int (A) is a function for converting the numerical value A into an integer.
[0088]
[Expression 1]

[0089]
Subsequently, the system control circuit 13 proceeds to step SP4, calculates the frame number specified by the frame number f from the initial setting position, then proceeds to step SP5, issues a read command with this frame number, Return to SP2. The identification of the frame number is set in the direction of the time axis from the initially set position or in the direction of going back the time axis according to the operation direction of the search dial 17F.
[0090]
Thus, in FIG. 10, the system control circuit 13 sets the search dial 17F to indicate the relationship between the operation of the search dial 17F and the playback position, where n is the total number of frames to be processed due to the relationship from the head position of each material. When it is fully rotated counterclockwise (indicated by symbol PA), access control is performed to reproduce the first frame to be processed (frame number 1), and when the search dial 17F is fully rotated clockwise (reference PB). The access control is performed so that the last frame (frame number n) to be processed is reproduced. Further, when the position is rotated clockwise by an angle γ from the position rotated fully counterclockwise (indicated by reference numeral PC), it is displaced by the number of frames k−1 corresponding to the rotational angle γ expressed by the following equation. The access control is performed so that the frame with the frame number k is reproduced.
[0091]
[Expression 2]

[0092]
As a result, the system control circuit 13 sets the upper and lower limits of the operable range of the search dial 17F so that the top and bottom time information in the reproduction result of the recording medium 4 to be processed corresponds. Thus, access to the recording medium 4 is controlled according to the operation direction and operation amount of the search dial 17F.
[0093]
In this way, the system control circuit 13 operates by operating the operating elements 17A and 17B for selecting the processing target in the state where the operating mode of the search dial 17F is set to the operating mode corresponding to the operating element (DPC) in this way. When the processing target is switched, the above-described processing procedure is similarly repeated. That is, the system control circuit 13 responds to the selection operation of these operators 17A and 17B with the values of the first and second time information in the set reproduction results corresponding to the upper and lower limits of the operable range of the search dial 17F. To switch.
[0094]
As a result, the system control circuit 13 can set the edit points easily by operating the operation elements 17A and 17B as necessary to narrow down the processing objects sequentially.
[0095]
(1-2) Operation of the First Embodiment In the configuration described above, in the editing apparatus 1, the AV signal S1 as the material to be edited is sequentially compressed in the data compression circuit 6 (FIG. 1). A frame number by a series of time codes is added and recorded on the recording medium 4 in units of frames. Further, at this time, a material list 14 necessary for accessing the material recorded in this way is generated by the editor 3, and this material list 14 is stored in the recording medium 4.
[0096]
The material recorded in the recording medium 4 in this way is read in units of frames by a read command to which a frame number specifying each material frame is added, and is decompressed as necessary and output to an external device. Also displayed on the monitor device 11. As a result, the editing apparatus 1 can execute an editing operation by setting an editing cut while checking the material.
[0097]
In this editing cut setting operation, in the editing apparatus 1, when the material side is selected by operating the operation element (SOURCE) on the operation panel 17 (FIG. 4), the material is an access to the recording medium based on the material list 14. In the display unit 16 (FIG. 3), the material side area assigned to the left half of the display screen in response to the selection process is displayed with high brightness. In this state, for example, when the operator (ALL) for selecting all materials is selected and then the operator (DPC) is selected, the search dial 17F is set to the operation mode of the slider. That is, the search dial 17F is set so that it can be operated by a predetermined angle range in the clockwise and counterclockwise directions with reference to the current position, and the frame located at the center of all the materials is reproduced from the recording medium 4.
[0098]
When the search dial 17F is rotated in this state, the first value and the last value of the time information in the reproduction result correspond to the upper and lower limits of the operable range of the search dial 17F. The access to the recording medium is controlled according to the operation direction and operation amount of the search dial 17F (FIG. 10). As a result, the editing apparatus 1 can select the frame to be processed from the first frame to the last frame by rotating the search dial 17F within a limited range of rotational operations, and roughly select the necessary frames. Is possible. As a result, the characteristics of the randomly accessible recording medium are fully exhibited, and it becomes possible to narrow down a desired frame much more rapidly than when the jog dial or shuttle dial is operated as in the prior art. It is also possible to grasp the entire image of the material simply and quickly.
[0099]
Thus, an edit cut can be set for the frame selected in this way by operating the edit point operator 17C as necessary.
[0100]
In addition, although the frame selected in this way is a frame at a desired location, when trying to select a frame before and after this, the operation elements (SHTL), (JOG), (DMC) are set. By selecting and switching the operation mode of the search dial 17F to the shuttle dial or jog dial operation mode and searching the previous and next frames, it becomes possible to select the desired material and frame as necessary. It becomes possible to register edit cuts by setting.
[0101]
At this time, the search dial operation mode is switched between the slider operation mode and the shuttle dial and jog dial operation modes, so that the characteristics of the randomly accessible recording medium can be fully exhibited, and the jog by the conventional video tape recorder can be performed. A desired frame can be easily selected by the same operation feeling as the shuttle dial.
[0102]
In addition, although the frame selected in this way is a frame at a substantially desired location, when trying to select a frame of the material before and after this, the search dial 17F as a shuttle dial or jog dial is operated. Instead, by operating the feed operators 17D (INDEX FWD) and (INDEX REV), it is possible to switch the material being reproduced in response to the operation of the operator 17D from the material currently being reproduced. In this case, it is possible to quickly select a desired material from many materials and to cue it.
[0103]
As a result, the operation mode of the search dial 17F is shuttled by selecting and operating the controls (SHTL), (JOG), and (DMC) for the material selected by operating the feed controls 17D (INDEX FWD) and (INDEXREV). By switching to the dial or jog dial operation mode and searching for the previous and next frames, it becomes possible to select a desired frame as necessary, and it is possible to set edit points and register edit cuts. .
[0104]
At this time, if one material being reproduced is selected as a processing target by operating the operation element (SHOT), it is possible to prevent the search dial 17F from being turned too much in the operation mode of the shuttle dial and the jog dial. Usability can be improved.
[0105]
When the operator (DPC) is selected with the desired material selected in this way, the search dial 17F is set to the operation mode of the slider, and this time, the search dial 17F can be operated with respect to the selected material. The top value and the bottom value of the time information in the reproduction result correspond to the upper and lower limits of the range, and access to the recording medium is performed according to the operation direction and operation amount of the search dial 17F. Is controlled.
[0106]
As a result, in the editing apparatus 1, the search dial 17F can be rotated within a limited range of possible rotation operations to select from the first frame to the last frame of one material, and the necessary material can be roughly grasped. In addition, it is possible to easily and quickly select a required frame.
[0107]
Therefore, in the editing apparatus 1, when the search dial 17F is operated according to the operation mode of the slider as described above, it is necessary to grasp the entire image of the material by sequentially switching the processing target from one material to one material. The frame to be played can be narrowed down more easily than the entire material.
[0108]
It should be noted that instead of narrowing down the search dial 17F for all the materials by the slide mode, a desired material is selected by the operation of the search dial 17F by the operation mode of the shuttle dial and the jog dial as in the conventional case, and then the operation element is selected. (SHOT), even if the search dial 17F is set to the slider operation mode for the selected material as a processing object by operating the operation element (DPC), the entire frame of the material is grasped and the necessary frame is determined from the entire material. In this case, after narrowing down the material in the same manner as in the operation of the conventional video tape recorder, the frame can be narrowed down by the slider function unique to the editing apparatus 1.
[0109]
By the way, although the material is selected in this way, there may be a case where the material is different from the desired material. In this case, the material to be processed is set near by the operation of the operation elements 17D (INDEX FWD) and (INDEX REV). The desired material can be selected by switching to the material, and the desired material can be selected from all the materials again by operating the operation element (ALL).
[0110]
In this way, a frame can be selected from a desired material, and a cut can be temporarily registered by operating the operation elements 17C (MARKIN) and (MARK OUT), and this cut can be edited by operating the operation element (ENTER). Can be registered.
[0111]
When registering the edit cut, when so-called previewing is performed, the processing target is switched to the temporarily registered cut by operating the operation element 17B (MARK), and this cut is monitored by operating the operation element 17E (PLAY) or the like. It becomes possible to do. At this time, the operation mode of the search dial 17F can be set to the operation mode of the shuttle dial and the jog dial, and the preview process can be executed in the same manner as an editing apparatus using a conventional video tape recorder.
[0112]
At this time, the search dial 17F is set to the slider operation mode by the operation of the operator (DPC), and this time, the temporarily registered cut is reproduced with respect to the upper and lower limits of the operable range of the search dial 17F. Is set so that the top value and the last value of the time information correspond to each other, and the access to the recording medium is controlled according to the operation direction and the operation amount of the search dial 17F.
[0113]
As a result, the search dial 17F can be rotated as necessary to easily grasp the entire image of one cut. In addition, by sequentially narrowing down the processing target of this search dial 17F to all materials, one material, and one cut, after grasping the overall image of the material and narrowing down the necessary frames from the entire material, the result can be simplified. It can be confirmed, and if necessary, it is possible to examine the temporarily registered cut in various ways through quick processing by returning to the original one material or all materials from the cut and confirming it. . This also makes it possible to fully exhibit the characteristics of a randomly accessible recording medium and improve usability.
[0114]
Thus, by repeating such processing, the editing apparatus 1 sequentially creates edit cuts from the material, further creates edit cuts from the editing results, and these edit cuts are sequentially registered to create the edit list 15.
[0115]
In the editing apparatus 1, when confirming the editing result by the editing list 15 created as described above, or when creating an editing cut further than the editing result, the processing target is switched to the editing result by operating the operator (PROGRAM). Thus, the recording medium 4 is accessed based on the editing list 15 instead of the access based on the material list 14 on the material side. In response to this selection process, the area on the edit result side assigned to the right half of the display screen is displayed with high brightness on the display unit 16 (FIG. 3).
[0116]
In this state, for example, when the operator (ALL) for selecting all materials is selected and then the operator (DPC) is selected, the search dial 17F is set to the slider operation mode, and the clockwise and counterclockwise directions are set based on the current position. The search dial 17F is set so that it can be operated by a predetermined angle range in the clockwise direction, and the frame located at the center of the editing result is reproduced from the recording medium 4.
[0117]
When the search dial 17F is rotated in this state, the top and bottom values of the time information in the edited result are set to correspond to the upper and lower limits of the operable range of the search dial 17F. Then, access to the recording medium is controlled according to the edit list 14 in accordance with the operation direction and operation amount of the search dial 17F (FIG. 10), thereby rotating the search dial 17F within a limited range of possible rotation operation. Therefore, it is possible to select from the first frame to the last frame of the editing result, and it is possible to easily and quickly grasp the entire image of the editing result. As a result, the characteristics of the randomly accessible recording medium can be fully exhibited and the usability can be improved.
[0118]
Even when the editing result side is set as the processing target, the editing apparatus 1 sets the editing points by sequentially selecting the editing cut and the desired frame from the whole as in the case where the material side is set as the processing target. Thus, a desired cut can be provisionally registered from the editing result, and further, the temporarily registered cut can be confirmed and registered in the edit cut.
[0119]
Further, by operating the operation element 17E, the jog dial, and the search dial 17F as a shuttle dial, the editing result can be confirmed as in the case of an editing apparatus using a conventional video tape recorder.
[0120]
Further, at this time, similarly to the case where the material side is set as the processing target, the search dial 17F is operated by the operation mode of the slider, and the processing target is sequentially narrowed down by operating the operation elements (ALL), (SHOT), and (MARK). In addition, the processing target is switched by operating the feed operation elements 17D (INDEX FWD) and (INDEX REV), so that the editing result, each editing cut, and the entire image generated from the editing result can be grasped easily and quickly. Preview, and by editing the processing target, each editing cut or the like can be examined by comparison with the whole image. This also makes it possible to fully exhibit the characteristics of a randomly accessible recording medium and improve usability.
[0121]
In this way, in editing work, such editing point setting and preview processing occupy the majority, thus improving usability in this way and dramatically reducing the time required for editing work. Can do.
[0122]
(1-3) Effects of the First Embodiment According to the above configuration, the upper and lower limits of the operable range in the search dial that is a rotary operator are the top and bottom of all materials, and the top of one material. By switching to correspond to the head and tail, etc., and controlling access to the recording medium in response to the operation of this operator, it is possible to easily grasp the whole image and quickly select a desired frame. As a result, the functions of the randomly accessible recording medium can be fully exhibited to further improve the usability, and the time required for editing can be shortened accordingly.
[0123]
Also, by switching the processing target depending on the material side and the editing result, not only when selecting a cut from the material, but also when checking the editing result, it is possible to grasp and confirm the entire image with a quick and simple operation. As a result, the functions of a randomly accessible recording medium can be fully exhibited to further improve usability, and the time required for editing can be shortened accordingly.
[0124]
Furthermore, with regard to such materials and editing results, the processing target can be sequentially switched by the same operation so that a desired frame can be narrowed down. At this time, the display is switched according to the corresponding display form on the material side and the editing result side. By displaying time information and the like, the editing apparatus 1 can be used by a unified operation, and the usability can be improved accordingly.
[0125]
Further, in this way, when the search dial is set to the slider operation mode and the processing target is switched, the processing target which is the material and the edit cut can be quickly switched by the operation of the operation elements (INDEX FWD) and (INDEX REV). In addition, it is possible to select a material and an edit cut. This also makes it possible to fully utilize the functions of a randomly accessible recording medium, further improving the usability, and shortening the time required for the edit work.
[0126]
At this time, the conventional jog shuttle dial and one operator are shared, so that the functions of a randomly accessible recording medium can be fully utilized and the usability can be improved. Similar usability can be ensured.
